-. To all whom it may concern.

- Beit known thatI, HUGH D. Enmorr, a

citizen 'of the United States, and aresident of Skamokawa, in the countyof Wahkia-kum and State of Washington, have invented a new and. ImprovedBell-Ringing Device, of

which the following is a full, clear and ex-;

act description. I

My invention relates more particularly to a fog bell, in which a fixedbell. is employed and is automatically sounded at predeterminedintervals.

The prime object of the invention is to provide in association with thefixed bell, an independent, revolubly mounted clapper or striking devicearranged to give a plurality of sounding strokes against the bell anydesired rapidity of succession, the striking periods occurring at thedesired intervals.

In carrying out my invention, use 1s made of a clapper or strikermounted on a driven shaft turning beneath and adjacent to the bell, andthe end of the clapperishmged to be normally maintained, by centrifugalaction, radial to the shaft, but yleldmg at 1ts pivot or hinge to passthe bell. The clapper shaft is driven from an electric'motor, n circuitwith which is a circuit closer comprising relatively movable contactmembers, the alternate makin and breaking of the circuit being efi'ectethrough the medium of a ratchet wheel which engages by successive teethwith one of the contact members, to press the same against the coactingmember, for closing the circuit, the member engaged by the toothgravitatmg from the contact position as the tooth of the ratchet wheelpermits said member to drop.

The invention will be more particularly explained in the specificdescription following. 1

Reference is to be had to the accompanying drawings forming a. part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a partly sectional side elevation of a bell and itsbell-ringing means constructed and arranged in accordance with myinvention; Fi 2 is a side elevation of a circuit closer an switchemployed in the circuit with the electric motor for actuating thebell-striking means; and Fig. 3 is a detail transverse section showingthe clapper and bell.

In constructing a practical embodiment of my invention in accordancewith the illustrated example, to any suitable frame 10 a bell 11 isfixedly secured'in any approved manner, as by a bolt or shank 12 and nut13. Below'and adjacent to the bell a shaft 14 is mounted in suitablebearings 15 on the frame 10. Secured to the shaft 14 is a radial arm 16,to the outer end of which is .hinged a clapper 17, the hinge connectionbeing established, in the present example,

by a pivot pin 18, which passes through the shank of the clapper 17 andthrough the arm 16. To actuate the shaft 1d an electric I motor 19 isprovided, suitably geared to the said shaft. In the present example abevel pinion 20 on the motor shaft meshes with a bevel gear wheel 21 ona vertical shaft 22, the opposite end of which is similarly providedwith a bevel gear 28 which meshes with a bevel gear wheel 24 on theshaft 14.

In order that at predetermined intervals the shaft 14 be given aplurality of revolually supported, as at 28, on any suitable base orframe 29, and gravitates into contact w1th the toothed periphery of theratchet wheel so as to be lifted by the successive teeth of the ratchetwheel, in the turning of the latter. The free end of the contact member27 lies adjacent to and beneath a second contact member 30, whichdesirably is pivoted as at 31 to any suitable bracket or equivalent 32.The conductor wires are connected respectively to the pivot 28 and tothe block32.

By the described construction, in the rotation of the ratchet wheel 25,the teeth thereof will gradually raise the member 27 until it contactswith the member 30 to complete the circuit. Upon the engaging tooth ofthe ratchet wheel passing beyond a shoulder 27 formed on the contactmember 27, the latter, will drop and break the circuit. By pivoting thesecond contactmember 30, the latter will yield to the rising movement ofthe member 27 after the latter has made contact so that the circuit willbe maintained closed suflicientlylong to result in the motor 19v givinga plurality of revolutions to the clapper shaft 14, and thus cause theclapper to strike the bell 11 a number of times in rapid successionbefore the breaking of the circuit. Thus the clapper will be actuated atintervals, which may be regulated according to the speed of rotation ofthe ratchet wheel, or the number of teeth. Any suitable switch 33, hereconventionally shown, may be employed also in the circuit to manuallyopen or close the circuit.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a device of the character described, a circuit closer, comprisin aratchet wheel, a contact member pivote at one endand extending over theratchet wheel, said contact member engaging the ratchet wheelintermediate of its ends, and a second pivoted contact member above thefree end of the first contact member and with which the said free endengages when raised by the ratchet wheel.

the shoulder of the second contact member to permit the said secondmember to have retrograde movement away from the first member upon themovement of a tooth beyond said shoulder. i

In testimony whereof I have signed my name to this specification in thepresence of two subscribin witnesses.
